Chevrolet is launching a new campaign in partnership with Klout, a company that measures a user's online influence, to promote the 2012 Sonic subcompact car among a targeted group of consumers.

Building on the success of a Klout campaign with the Chevy Volt in Chicago, Chevy is again partnering with Klout, this time to implement the first national automotive Klout Perk to date.

The promotion, which begins today, enables qualifying Klout users in Chicago, San Francisco, New York, Atlanta, and Dallas to sign up via the Klout Perks Program to drive the all-new Sonic. Each Perk is a three-day vehicle loan granted between Nov. 11 and Dec. 14.

"We are aiming the Sonic squarely at consumers who are part of the Millennial generation," said Carolin Probst-lyer, manager of digital consumer engagement at Chevrolet. "Partnering with Klout allows us to reach this audience, encourage them to get behind the wheel of a Sonic, and use social media to share their driving experiences."

"The Klout Perk we offered earlier this fall for the Chevy Volt was one of our most successful campaigns to date," said Garth Holsinger, vice president of sales at Klout. "An experiential opportunity like this, taking home an all-new 2012 car, is a very special reward to influencers. We look forward to hearing about their exciting journeys on- and offline."
